Specification forming p ert of Letters I atent No. 11,064,` dated June 13, 1854; Ressued November 16,` 1,858, No. 624.

T0 all whom t may concern Be it known that I, GEORGE P. GORDON, of the city, county, and State of New York, have invented certain new and useful Improvements in Printing-Presses; and I do` hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is a side view of my improved press. Fig. 2, is also a side view of ditto, the side shown being opposite to that shown in Fig. l. Fig. 3, is a vertical longitudinal section of ditto, the plane of section being through the center, or nearly at that point. Fig. 4, is a detached back view of the fly. t

Similar letters of reference indicate corresponding parts in the several figures.`

This inventionrelates to certain new and useful improvements in printing presses, and consists, 1st, in the employment or use of a fly having a rotary reciprocating Inotion, and arranged as will` be hereafter shown, for the purpose of relieving the sheet from the type when printed, or removing the printed sheets, and piling `them upon the fly board; 2d, in giving with one inking cylinder, two `distributions to the inking rollers, for each impression, one prior to the passing of the `form and one prior to the repassing of theform; 3d, in the combination of a spiralspring, connecting rod, and crank motion, for operating the bed or carriage, as will be hereafter shown.

To enable others skilled in the art, to`

make and use my invention, I will proceed to describe its construction and operation.

A., Figs. l and 3, represents the frame of the press, the upper part ofwhich is inclined, and, B, is a swinging or vibrating frame, attached to the frame, A, by pivots, (a), a pivot passing through each side piece ofthe frame. The vibrating frame, B, is directly over the upper and inclined portion of the frame, A, and a spring, (p) is at-` tached to the frames, B, and A, see Figs. 2 and. 3.

t Within the vibrating frame, B, there1 is a `(b), are' stops, (s), (s), one of which is shown in Figs.` 1, 2, and 3. `The top and is attached by a joint or pivot, (c), to the' lower end of the bed or carriage, C, and the opposite end passes through an eye, (d), attached to the side of the toothed wheel, D,

. near its periphery. A nut, .(e'), is upon the lower end of the rod. Around the connecting rod, H, there is a spiral spring, (f), the upper end of which bears against the shoulder of the point, (c), and the lower end against the eye, (d).

I, is a curved arm attached to the vih-rat ing frame, B, the lower end of the arm, I, is about on a line with the periphery of the toothed wheel, D, directly over its center.

J, Figs. l, and 3, is a toggle attached by a pivot, (g), to one side of the toothed wheel, D. i

K, Figs. l, 2, and 3, is a frame containing two inking rollers, (L), K, has a shaft, (i), passing transversely through it, the ends of said shaft, (i), working loosely in the side pieces of the frame, A. At the lower ends of the side pieces of the frame, K, are rollers, |(j),-one roller to each side piece.

In the frame, A, and directly below the inking rollers, (h), is'placed the inking cylinder, L, against which the inking The frame,

rollers,` (h), (7L), bear when not operated upon by the movement of the bed or carriage, C, as will be p esently shown.

M, is a fly attached to the upper part of the frame, A, see Figs. l, 2` and 3. The fly is in the form of a segment of a cylinder and extends across thekwhole breadth of the frame. On one end of the fly there is a pinion, N, which gears into a segment rack, O, at the upper end of a lever, P, which has its bearing or fulcrum upon the shaft, F, of the pinion, E, and fly wheel, G. The lower end of the lever, P, lits in a ground cam, Q, which is hung on the aXle of the toothed wheel, D, see Fig. 2. The fly, M,

is provided with nippers, v(la), which are attached to a rod, (Z), operated by a spring, (m), and pin, (n), see Fig. l.

R, is a fly board placed underneath the fly, M. v

Operation: The paper is placed upon the upper part of the frame, A, at Z, see Fig. l, the red line denoting the sheet of paper, and mot-ion is given the shaft, F, in any proper manner, and the connecting rod, H, moves the bed or carriage, O, which contains the form, upward, and over, the paper; when at this point, the toggle, J, acts against thelower end of the arm, I, and forces the upper end of the vframe, B, toward the frame, A, and the form is pressed'upon the paper, the bed or carriage containing the form remaining stationary during the time the impression is given, in consequence of the eye, (c), acting against the spiral spring, (f), upon the connecting rod, H, and the upper'part of thebed or carriage bearing against the sto-ps, (s), (s), upon the return, or downward motion of the bed or carriage, the nippers, (70), hold the printed sheet in its proper place upon the frame until the type is freed from it by the spring, (p), and the liy, by the operation of the cam, Q, pinion, N, and rack, O, then revolves a part of a revolution backward, and carries the sheet around with it, and deposits it upon the ily board, R, see Fig. 3. As the bed or carriage, C, passes downward, the sides of the bed bear upon the rollers, (j), of the frame, K, and the nking rollers, (it), (7L), are, in consequence, lifted from the inking roller and bear against the What I claim as new, and desire to secure by Letters Patent, is

l. The employment or use of a rotating reciprocating fly, arranged substantially as shown, for the purpose of relieving, or of removing and piling the sheet after it is printed.

2. I claim giving with one` inking cylinder, two distributions to the inking, rollers for each impression, viz: one prior to the passing of the form, and one prior to the repassing of the form.

3. I claim the combination of the spiral spring, (f), connecting rod, H, and crank motion with the stops, (s), (s), for operating a bed or carriage, and giving the necessary dwell or cessation of movement to a bed or carriage during the time the impression is made, the above parts beingarranged as herein shown, or in an equivalent manner.
